BUILDING BLOCK.

Application filed March 16, 1926. -Serial No. 95,132.

This invention relates to building blocks or bricks and has for one of its objects to provide a brick which may be made of clay,

, concrete or other suitable composition material, which may be used in the construc tion of hollow walls and which is provided with suitable breaking slots and notches whereby it may be readily fractured along predetermined lines to provide various shapes for use in construction details.

A further object of the invention is to provide a brick of the character described having spaced parallel face portions adapted to form the inside and outside wall faces, which face portions are connected by a transverse web thusforming a brick \which is substantially Lshaped in plan, the said transverse web being provided with a central longitudinally extending breaking slot and with suitable transverse breaking notches adapting, the brick to be broken into various shapes as above mentioned.

With the above and other objects in view which will appear as the description proceeds, the invention consists in the novel details of construction, more fully hereinafter described and particularly pointed out in the appended claims.

Referring to the accompanying drawings forming a part of this specification in which like reference characters designate like parts in all the views;

Figure 1 is a top plan view of a brick or block constructed in accordance with the present invention;

Fig. 2 is an elevational view of the brick shown in Fig. 1;

Figs. 3, 4i, 5, and G are diagrammatic plan views illustrating the various forms which may be obtained by breaking the brick, shown in Fig. 1, along predetermined lines established by the breaking notches and slot;

Fig. 'i' is a fragmentary perspective view showing a portion of a wall formed of bricks constructed in accordance with the present invention; and,

Figs. 8 and 9 are diagrammatic sectional plan views showing the use of the brick in connection with difierent forms of window frames and plastering.

Referring more especially to the said drawings, the numeral 10 indicates generally a brick, constructed in accordance with the present invention, with the parallel spaced face portions or members 11 and 12, which are connected by which is provided.

the transverse web member 13 The face members 11 and 12- in elevation are of substantially the dimensions of standard bricks which is provided at its ends with V-shaped notches 15 extending partially into the face members 11 and 12, as shown. The said notches 15 merge into laterally extending notches 16 which are preferably located substantially in alignment .with the inner faces 17 and 18 of the face members 11 and 12, asshown. The outer surfaces 19 of the web member 13 are preferably connected to the surfaces 17 and 18 of the members 11 and 12 by fillets of suitable radius which fillets,

however, are provided with breaking notches 20 in substantial alignment with the breaking notches 16, as will be clearly understood from Fig. 1.

The provision of the breaking notches makes it possible to fracture the brick along the predetermined lines, indicated by the broken lines A, B, C, D, E and F, as will be readily understood, whereby it is possible to obtain the various shapes illustrated in Figs. 3, i, 5 and 6. In other words, by suitably breaking the brick, shown in Fig. 1, along the proper combinations of the lines A, B, G, D, E and F, fragments such as are shown in the said Figures 8, 1, 5 and (5 may be obtained for various construction detail work without the necessity of having to manufacture special shapes for such work. In other words, a fragment presenting an 8 by 2 face as shown in Fig. 3 may be obtained by fracturing the brick shown in Fig. 1, along the lines C and D, for example, while a fragment for presenting a 2 by 4: face as shown in Fig. 4 may be had by fracturing along the lines A and C. The form shown in Fig. 5 may be obtained by fracturing along lines B and E while that shown in Fig. 6 is obtained by fracturing along lines A and B. 1

In Fig. 7, here is shown diagrammatically, a portion of a wall made up of bricks constructed in accordance with this invention. It will be noted that a door frame 2:") is shown diagrammatically and that-behind ion v the said frame, the spaces between the face rods 29 incorporated therein.

. ing' applied on furrin Fi 8 the window members 11 and 12 of the bricks may be filled with concrete, :as indicated at 26 and that suitable'reinforcing rods27 may be embedded in the said concrete. Likewise, at corners the bricks may also be filled with concrete, as indicated at 28 and reinforcing The, inner faces 12 of the bricks may receive a suitable coat of'plaster 30, since the plaster will'effectivelybond therewith, as will be readily understood.

In Figs. 8 and 9 there is illustrated diagrammatically the use of the bricks adjacent window frames wherein two different methods of plasterin are employed. .In ame 31 is provided witi a plaster jamb 32, the plaster being applied directly to the face member 12 of the brick. It will be noted in this form that the brick is used without fracturing.

In Fig. 9 the window frame 35 is provided with one form of well own building construction'. In thiscasel a brick fragment similar to that shown in Fig. 5 is used adjacent the window frame 35.

It will thus be seen that bricks constructed as above described readily lend themselves to use in' connection with widely varied forms-of building construction and that it is possible to provide brick shapes by fracturing the standard bricks to meet the various conditions which arise, without the necessity of making special shapes. 7

When employed in its entirety, the brick presents an inside and outside face connected by a web so that one unit forms the entire' thickness of the wall and there are' no through mortar joints in the wall. When the spaces between the inner and outer face members 11- and 12 are not filled with concret'e or other similarmaterial, an insulat ing air space is providedwhich amounts'to approximately percent of thevolume of the wall. This space may, of course, be filled,

if desired, with suitable thermal insulationor sound deadening material without in any 38, inaccordance mg breakin slot and said face members wa1 effecting the other properties of the we While one form of the invention has been illustrated and described, it is obvious that those skilled in the art may vary the precise details of construction without departing from the spirit of the invention an therefore, it is not wished to be limited to the above disclosure except as the invention is defined by the claims.

What is claimed is:

1. A building block. comprising face members connected by an inte rally formed web portion, said web portion being'formed with a breaking slot andone of said face members having a breakingnotch communicating with said slot, and said Web being further formed with breaking notches extending laterally from said slot and adjacent to the breaking notch in said face member.

2. Abuilding block comprisin a pair of spaced face members connected y an interally formed web member, said web being ormed with a central longitudinally extendhaving brea ting notches extendin axially with said slot and communicating t erewith, said web being further formed with breaking notches extending laterally from said slot adjacent said face members, and the exterior surfaces of said web being provided with other breakin notches extending inwardly toward sai slot and aligned with said last named notches.

3. A building block substantially I-sha ed in plan and com rising a pair of para el spaced'face mem ers connected by an integrally formed web, said web being formed .with a central elongated breaking slot en largled at its ends toprovide axially and latera y extending breaking notches, said laterally extending breaking'notchesbei in substantial alignment with the rear sufiiices ofsaid face members and said axially extending notches extending into the rear faces of said face members. p

In testimony whereof I aiiix my signature.
